He looks better with the head on...
...and so is Casper!!
Who was Casper when he was alive?
...and the Flying Dutchman!! (hey, why's he not haunting Bikini Bottom?)

"I'll scare Spongebob first, then I'll steal your soul. Wahahaha."
...and Danny Phantom (well, he doesn't really qualify as a ghost since he's part human)!!

Ghosts. People say that the dearly departed haven't really departed yet. Some of them have, but the others have, as live 'uns say, unfinished business on Earth. They cannot rest before all their accounts are in order.
Now, why did I make a post 'bout ghosts? Because I played the Ouija Board last night. Okay, so it was a computer program Ouija board on www.agame.com, but it was fascinating enough to be quite spooky.
So I was playing again just now (actually, I don't know if that was playing) and I was asking a ghost the time she died. She said she died in year 1128 and she died by battle.
It just roused my curiosity of the paranormal world. How did the idea of ghosts come into being? How do ghosts communicate with humans if they're dead? And my main question, which has remained unanswered since I was 5 years old: ARE GHOSTS REAL??
I found this article about how science proves that ghosts are real:
Science and Ghost Hunting
When scientists debunk ghosts their first statement is usually, “there is no scientific proof of the existence of ghosts.” This is wrong. There is scientific proof. Science even has theories that explain something must be happening beyond what we know and what we can see.
Albert Einstein (1879-1955), Time Magazine's Man of the Century and one of the greatest minds the world has known, taught us that energy cannot be created or destroyed. It can only be changed from one form of energy into another form of energy. This means that no matter what is done energy cannot be destroyed.
Human beings have both electrical and chemical energy in our bodies. We are organically designed to carry our electrically charged brain and nervous systems. When we die our chemical bodies begin to break down and decompose. The organic side returns to where it came from - energy changing into a different form of energy as Einstein's law says. So what happens to the electrical energy that flows through our brain? It can't simply disappear or fade away out of existence. That would break the laws of science. That energy has to still be somewhere only now it has changed into a different form of energy. What happens to the energy is really determined by personal faith. No one knows exactly what waits beyond this life. What we do know, thanks to science, is that the electrical pulse energy in each human being will always exist because as a rule it “cannot be destroyed.”
Another great scientist who believed in life after death was Thomas Edison, (1847-1931). Edison was a genius ahead of his time. He invented the light bulb, phonograph, typewriter, electric motor, stock ticker, and 1093 other patented inventions. One of the inventions that he worked on at the end of his career was a secret project, a machine that would let the living see and communicate with the souls of the dead.
Edison believed that that the soul was made up of what he referred to as “life units.” These microscopic particles of life units could rearrange into any form. They retained full memory, personality and were indestructible. Edison's machine would detect these life units in the environment and allow living individual to communicate with the dead. He put many years of hard work into his new creation, but sadly, he died before it was finished. Some called Edison crazy. Others thought that he was onto something bigger than the idea of the light bulb. They believed that if he would have had a little more time, we might all today be living in a very different world.
It's been found that in almost every ghost haunting and poltergeist that there are certain electrical elements at work. Using EMF detectors, ghost hunters can monitor these electrical forces. These devices can examine and record even the smallest fluctuation in the surrounding electromagnetic field. Everything gives off some kind of electromagnetic field, even our own bodies. Electrical appliances, like television sets and computers give off higher distortions than a lamp or a toaster would. When ghosts are present there are higher levels of electromagnetic distortions. Many times the distortions are so high that they interfere with the working abilities of computers systems and audio/video equipment. High levels of static electricity are also detectable.
Recording temperature changes is another scientific way of detecting the presence of ghosts. Fluctuations of more than 10 degrees have been recorded in small areas of rooms with constant temperatures. It's a scientific fact that there has to be some form of energy present to alter the temperature. Temperature does not change unless "something" is affecting it one way or the other. In many ghost sightings witnesses report feeling a cold spot. This could be caused by the fact that light does not seem to reflect correctly off of most ghosts, which also gives them a dark form. The light seems to be absorbed into the ghost. The theory is that ghosts absorb both light and heat energy causing the general area around that ghost to be several degrees cooler. There are also hot spots recorded, which could be just the reverse affect occurring. Instead of soaking up the light and heat the ghost is reflecting it back, causing the area to be warmer.
These unexplainable electromagnetic fluctuations and temperature changes are scientific evidence that something is happening. Ghosts are real.
Freaky. Abnormality is often ignored, frowned upon, and feared today, the era of knowledge and fact. We think we know everything, but this is just inexplicable.
Here's another article I found. But this time, it's disproving the existence of ghosts.
Ghosts are part of the traditions and folklore of all cultures and countries in the world. Most towns (old ones more frequently) own at least one haunted house or ghostly area.
Many scientists who are trained in paranormal phenomena have tried to prove or at least explain in part the reason for the presence of what affected people call "poltergeist" (noisy spirits) and ghosts.
Skeptics basically use the principle of Occam's razor, which states that the simplest adequate explanation for any event is the most likely explanation.
For instance:
-The typical haunted house is an old place with many years out of maintenance, this create creaking sounds, howling noises created by the wind thru open / broken windows, hollow spaces generate eco sounds, deformed shapes or ragged curtains create spectral shadows or shapes, rats can make scary noises.
-A person or group of persons under a stressful situation (i.e. visiting a place where a murder has been commited) can become easily panicked (and panic can be very contagious). When you are in a creepy place, in the darkness and you are stressed your senses (mainly vision and hearing) can be very deceptive.
-If you are in a forest on a Camp, and somebody tells stories about something creepy that happened in that forest, chances are if you stay awake (and if you are alone is worst) you will transform every tree branch on arms and legs, and the wind will be much more like a howl or haunting scream.
Finally, again this question has no answer, BUT I can say that ghost or no ghosts being real, our imagination can be very tricky and can play games with us. If you don't believe this try staying alone at home one night and rent 2 or 3 good horror/suspense movies (i.e. The Sixth Sense, The Changeling and Stir of Echoes), and let me know if you don't start feeling that someone is looking behind you, or something moves in the shadows in the corner of your eye, or something like that. Most of the people I have challenge to do this, do not even finish the first movie and end up knocking my door to stay overnight. And this doesn't mean that they have ghosts at their homes :)
